Abstract

The invention discloses a thousand-seed weighing instrument based on machine vision, comprising a CCD (Charge Coupled Device) camera, a shadowless light source, a rotary unloading mechanism and a precision electronic scale, wherein the CCD camera is used for acquiring an image of seeds; the shadowless light source is used for supplementing light during image acquisition; the rotary unloading mechanism comprises a tray, an objective table and a bin shell; the tray and the bin shell are connected by screws to form a bin, the bin is used for accommodating crop seeds to be counted, a guide rail is arranged below the tray, a circle of guide rail trough is arranged on the objective table, and the tray can rotate on the objective table via the guide rail; the rotary unloading mechanism is used for scattering seeds and controlling the seeds to fall, and the precision electronic scale is used for weighing seeds. The thousand-seed weighing instrument overcomes the defect of low thousand-seed weight counting efficiency of existing crop seeds, and can fulfill the purpose of automatic measurement of crop thousand-seed weight.

Description

technical field [0001] The invention relates to the technical field of automatic counting and weighing of seeds, in particular to a machine vision-based seed thousand-grain weight instrument. Background technique [0002] In research and production in the field of agriculture, it is often necessary to count and test seeds of a small amount of crops such as grain, vegetables, and medicinal materials, and accurate counting and weighing are the keys to test seeds. Thousand-grain weight is the weight of 1,000 seeds, which is an important basis for the agricultural planting test. According to the measurement requirements of GB / T 5519-2008 grain and bean thousand-grain weight, thousand-grain weight = (1000x m 0 ) / N,m 0 is the mass of the sample, and N is the grain number of the sample. [0003] At present, there are many types of thousand-grain weight instruments and equipment at home and abroad, but most of them adopt electromagnetic vibration sorting method, which has the adva...
